1. In a patient with chronic obstructive pulmonary disease (COPD), which of the following interventions is most important?
- A. Encouraging the patient to stop smoking.
- B. Administering bronchodilators.
- C. Monitoring oxygen saturation.
- D. Providing nutritional support.
Correct answer: C
Rationale: Monitoring oxygen saturation is the most important intervention in a patient with COPD because it helps assess the adequacy of oxygenation. In COPD, patients often have compromised lung function, leading to decreased oxygen levels in the blood. Monitoring oxygen saturation allows healthcare providers to promptly identify and address any potential hypoxemia, which is vital in managing COPD exacerbations. While encouraging the patient to stop smoking (Choice A) is critical for long-term management, monitoring oxygen saturation takes precedence in the immediate care of a COPD patient. Administering bronchodilators (Choice B) and providing nutritional support (Choice D) are important aspects of managing COPD but are secondary to monitoring oxygen saturation, which directly impacts the patient's oxygenation status.
2. A client with chronic renal failure is receiving sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?
- A. Hyponatremia.
- B. Hypokalemia.
- C. Hyperkalemia.
- D. Hypocalcemia.
Correct answer: C
Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.
3. The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient’s electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?
- A. Evaluate the patient’s urine output.
- B. Contact the provider to order arterial blood gases.
- C. Request an order for an initial potassium bolus.
- D. Suggest a diet low in sodium and potassium.
Correct answer: A
Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.
4. The nurse is planning care for an older adult client who experienced a cerebrovascular accident several weeks ago. The client has expressive aphasia and often becomes frustrated with the nursing staff. Which intervention should the nurse implement?
- A. Teach the client the use of basic sign language
- B. Speak slowly to the client
- C. Encourage the client's use of picture charts
- D. Ask the client simple questions
Correct answer: C
Rationale: Encouraging the client's use of picture charts is the most appropriate intervention for a client with expressive aphasia. Picture charts provide visual cues that can aid in communication and reduce frustration for the client. This intervention can help the client express their needs and thoughts effectively. Teaching sign language (Choice A) may be challenging and not as practical in this situation as it may not address the specific communication barriers caused by expressive aphasia. Speaking slowly (Choice B) may not fully address the communication difficulties associated with expressive aphasia. Asking simple questions (Choice D) may not be effective as the client may have difficulty understanding and responding due to the nature of expressive aphasia.
5. A patient asks the nurse about taking calcium supplements to avoid hypocalcemia. The nurse will suggest that the patient follow which instruction?
- A. Take a calcium and vitamin D combination supplement.
- B. Take calcium along with phosphorus to improve absorption.
- C. Take calcium with antacids to reduce stomach upset.
- D. Use aspirin instead of acetaminophen when taking calcium.
Correct answer: A
Rationale: The correct answer is to take a calcium and vitamin D combination supplement. Vitamin D enhances the absorption of calcium in the body, making it an essential component for calcium utilization. Choice B is incorrect because calcium and phosphorus have an inverse relationship, where an increased level of one mineral decreases the level of the other, so taking them together may not be beneficial. Choice C is incorrect because antacids often contain magnesium, which can promote calcium loss instead of absorption. Choice D is incorrect because aspirin can alter vitamin D levels and interfere with calcium absorption, so it is not recommended when taking calcium supplements.
